STAND-PIPE CONNECTION FOR OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 772,804, dated October' 178, 1904.

Application led March 24, 1904:.

To @ZZ whom t may concern:

Be it known thatI, JOHN A. HooPER, acitizen of the United States, residing at Southard, in the county of McKean and State of Pennsylvania, have invented new and useful Improvements in Stand-Pipe Connections forv Oil-Wells, of which the following is a speciiication.

My invention pertains to stand-pipe connections for oil-wells, and has relation to an improved means to prevent the bending and breaking of the stand-pipe or tubing through the action of the polish-rod and the movement of the walking-beam.

In the usual form of devices used for pumpving oil from oil-wells the polish-rod is'connected to one end of the walking-beam andpasses through the stand-pipe and tubing and is connected with the suction-rod in the well.

-quently broken above the casing-head and in some instances below the casing-head.

The object of my present invention is to pro-v vide means to prevent-the bending and breaking of the stand-pipe or the tubes'.

In the accompanying drawings, Figure l is a side elevation'iof my invention, showing it in connection Withia walking-beam. Fig. 2 is a detached longitudinal sectional view of my improved flexible connection. Fig. 3 is a detached view of one of the clamps for holding the flexible. connection to the stand-pipe and tube.

Referring nowto the drawings, 1 indicates the ordinary walking-beam, which has one end connected with any suitable means 2 for the purpose of reciprocating it, and 3 is the casing-head of an oil-well'. Projecting fromthe casing-headis a portion of the tubing 4, and 5 is the stand-pipe, provided with the usual stufling-box 6 at its upper end. Passing through the4 stand-pi pe 5 and the tubingl; and connected with the sucker-rod in the well(not Serial No. 199,723. (No model.)

here shown, as they are so Well understood.) is the usual polish-rod 7 This polish-rod is suit-ably connected -in the usual and wellknown manner to the 'free end 8 of the wall;- ing-bearn 1.

'Instead of connecting the stand-piperigidly with the projecting end of the tubing 4, in which rigid connection it necessarily follows that there is a vibration of the standpipe and tube 4, owing to the fact that the free end of the walking-beam describes the segment of a circle, I provide a flexible connection 9 between the lower end of the standpipe 5 and the projecting end of the tube 4. This flexible connection may consist of rubber, canvas, or the ordinary hose tubing and, as here'shown, is a section of a flexible tube, having its respective ends clamped to the ad# jacent ends of the stand-pipe and the tube through the medium of clamps 10. From the foregoing vit will be readily observed that this flexible connection permits the stand-pipe to vibrate independent of the tube 4C, thus preventing a bending of either the tube or thev stand-pipe and also preventing a breaking of either of the parts. Furthermore, this flexible connection relieves a great deal of friction and wear, and hence produces a construction which is easier in its operation.

Owing to the fact that the stand-pipe 5 vibrates, it is'necessary to provide for this Vibration in some manner in the connection l1,

through which the oil flows from the standpipe to the oil-tank l2. This is accomplished by making the connection l1 either of a eXible tube or having its ends resting loosely upon the oil-tank and permitted to move back and forth. v

Since the oil is drawn from the well by the sucking or pumping apparatus through the stand-pipe 5, itfis necessary that the flexible joint should be a tight one, and in the construction here shown a perfectly tight flexible joint is provided.

. Having thus described my invention, what I claim, and desire to secure by Letters Patent, ism v l. In a device of the character described,

the .combination with an oil-well tube, of a IOO flexible connection connecting the adjacent ends of the stand-pipe and the oil-well tube and holding them out of engagement, a walkingbeam, and a polish-rod passing through the stand-pipe and connected with the pumping apparatus, substantially as described.

2. Ilka device of the character described, the combination with an oil-well tube, of a stand-pipe, a Hexible connection between the tube and the pipe, a walking-beam, a polishrod passing' through the stand-pipe and connected at one end with the walking-beam, and at its opposite end with the pumping apparatus, and an oil-exit connected with the standpipe at a point above its iexible connection and connected with a receiving-tank, the said oil-exit being so constructed as to permit a vibration of the stand-pipe, substantially as described.

3. In a device of the character described, the combination with an oil-well tube, oi a stand-pipe, a iexible tube passing over the tube and the stand-pipe, clamps passi n around the Hexible tube and clamping it to the welltube and the stand-pipe, a walking-beam, a polish-rod having its upper end secured to the walking-bean'l and passing through the stand pipe, the iexible connection, the well-tube, and having at its lower end the pumping apparatus, and an oil-exit connected with the stand-pipe at a point above the flexible tube.

1n testimony whereof 1 have hereunto set n1 y hand in the presence of two subscribing witn-esses.

JOHN A. HOOPER.
